Let me detail the mods: Socketed output capacitor to easily adjust bass response. Toggle-able sockets, so you can easily swap between 2 different output capacitors. All AB-Synths come with the bass mod these days, and this was an extra mod I had done for even more low end. Awesome Awesome pedal.

From standard, heavy fuzz, to glitchy, oscillating, synthed out goodness, this pedal kicks serious behind. Just a little too fuzzy for me, and I settled on a woolly mammoth clone, if that gives you any idea how fuzzy it is. It's awesome no doubt, but not particularly useful in a modern rock/top 40 situation
